Such watches are known as “PDS” watches. PDS tornado (TOR) watches are issued when the forecaster has high confidence that multiple strong (F2-F3 on the Fujita Scale) or violent tornadoes (F4-F5 on the Fujita Scale) will occur in the watch area, while PDS severe thunderstorm (SEV) watches are issued when there is a threat of a high end “derecho” (e.g. Johns and Hirt 1987, Coniglio et al. 2004) ...

A personality disorder can be considered to be a generalized pattern of behaviors, cognitions, and emotions that is enduring, begins in adolescence or early adulthood, remains stable over time, and generates stress or psychological damage. The current focus on personality disorders (PDs) is found in Section II of DSM-5 and is unchanged compared to DSMIV, except that the PDs were removed from th...

Proof-Number (PN) search is a best-first adversarial search algorithm especially suited for finding the game-theoretical value in game trees. The strategy of the algorithm may be described as developing the tree into the direction where the opposition characterised by value and branching factor is to expect to be the weakest. In this chapter we start by providing a short description of the orig...

As a strategy to prevent the progression of diabetes mellitus, it is important to screen out the subjects who will develop a pre-diabetic state (PDS) in the future. To find out the potential risk factors for PDS, we employed the values of fasting plasma glucose and hemoglobin A1c (HbA1c), which are routinely measured in our health checkup. We selected 3,879 individuals who had normal glucose re...

OBJECTIVE To compare the number of surgical site infections (SSIs) registered after hospital discharge with respect to various surgical procedures and to identify the procedures for which postdischarge surveillance (PDS) is most important. DESIGN Prospective SSI surveillance with voluntary PDS. Recommended methods for PDS in the Dutch national nosocomial surveillance network are addition of a...

BACKGROUND AND OBJECTIVES The common technique used in securing the base of the appendix is Endoloop ligature (Ethicon, Somerville, NJ, USA). Vicryl (polyglactin 910) (Ethicon) and polydioxanone (PDS) (Ethicon) Endoloop ligatures can be used. There are potential benefits of the use of PDS Plus (Ethicon) Endoloop ligature. However, the use of different materials may vary in terms of inflammation...

BACKGROUND Recent guidelines concerning the treatment of personality disorders (PDs) recommend diagnosing PDs in adolescents. However, it remains unclear whether these guidelines influence the current opinions and practices of mental health care professionals. METHODS Five hundred sixty-six psychologists completed an online survey concerning PDs in adolescents, of whom 367 professionals repor...

BACKGROUND The association of psychiatric disorders (PDs) with other PDs and medical disorders (MDs) has been insufficiently explored in children and adolescents. OBJECTIVES To estimate medical and psychiatric comorbidity present in children with PDs and to determine the medical service usage of children with PDs. DESIGN We use administrative health care data to describe the health care pro...

Pendrin mutations cause enlarged vestibular aqueducts and various degrees of sensorineural hearing loss. The selective abolition of pendrin causes dilation of the membranous labyrinth known as endolymphatic hydrops, loss of the endocochlear potential, and consequently loss of hearing function. Because Na+ transport is one of the most important driving forces for fluid transport, the epithelial ...
